SPLIT-SPRAY NOZZLE.

Specification of Letters Patent.

Patented J uly 31, 1917.

Application filed November 15, 1916. Serial No. 131,381.

To all whom it may concern.

Be, it known that I, GEORGE P. SYMoNDs, a citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Split- Spray Nozzles, of which the following is aspecification, reference being had therein to the accompanying drawing.

My present invention refers to a spray head, the object of which is to diffuse the water widely so that the greatest amount of water surface may be presented to the action of the air. The invention has a wide variety of uses, the preeminent one of which is that of cooling towers wherein it is desirable to distribute the water and bring it into contact with a large amount of air in the cooling process. In so doing it is essential that the emission slot in the spray nozzle should be as large as possible so that it will not become easily clogged with debris of various kinds. The invention, therefore, consists essentially in the combination with a spraying nozzle of one or more splitters for cutting or subdividing the main stream of water issuing from the nozzle into a plurality of sheets or vapor zones so that a large aqueous surface will be offered to the cooling action of the circulating currents of air; and further the invention comprises numerous details and peculiarities in the construction, arrangement, and combination of the various parts, substantially as will be hereinafter described and then more particularly pointed out in the claims.

In the accompanying drawing illustrating my invention:

Figure l is a side elevation of my improved spray head;

Fig. 2 is a longitudinal section on the line 2, 2 of Fig. 1;

Similar characters of reference designate like parts in both figures.

The spray head is composed essentially of a pipe 1 terminating in a flattened end 2 having therein a long flat orifice 3 whose walls are parallel to each other, as shown in Fig. 2, so that the stream of water coursing through the pipe 1 and striking the flattened end 2 will emerge through the flat slot 3 in a substantial sheet of water. The slot 3 is a fairly wide one, say one-eighth of an inch in width in ordinary constructions, so that it will not become easily clogged with debris,

it being necessary in cooling towers and other places where my improved spray head may have peculiar value that the action of the water should be free and not easily obstructed by foreign matter.

Supported 0n the fiat slotted nozzle 2 in any convenient manner is a splitter 4 which consists of a suitable yoke which is attached at the sides of the slotted nozzle 2 by being cast integral with the pipe 1 or otherwise formed, and the portion of the splitting de vice 4 immediately above the outlet slot 3 is formed with a knife edge 5. Said knife edge being directly above the slot 3 will be struck by the sheet of Water issuing from the slot 3 and will consequently divide said sheet of water into two thin sheets, each approximately half the thickness of the opening 3 in the flat nozzle 2. The knife edge 5 cleaves the volume of water in twain or so splits it that half is diverted in one direction and half in another, and two vapor zones of substantial size are created so that the diflusio-n of the water is very large and a great amount of water surface is brought into contact with the currents of air circulating or flowing past or around the spray head. In the present example of the invention where I have indicated that the size of the slot 3 may be about one-eighth of an inch in width, it will be seen that the thin sheets of water into which the main stream is split will be in thickness approximately half the width of the slot 3, or say one-six teenth of an inch each.

The splitters may be multiplied if desired so as to increase the subdivision and enlarge the water surface; also they may be made in a different form from the knife edge 5,.

if only a sharp edge is furnished in the path of the issuing stream of water, and it must be kept in mind all the time that the primary stream coming through the slot 3 must be of some substantial size for the slot must not be small enough to be interfered with by debris and foreign matter, such a stream being essential in cooling towers and various other locations where the water must be brought into very intimate contact with the air. It will, therefore, be perceived that many changes in the precise construction and arrangement of the various parts may be made Without exceeding the scope of my invention.

Having thus described; invention, What I claim as new and desire to secure by Letters Patent, is:

1. In a spray head, the combination with a flat slotted nozzle, of a sharp edge located opposite thereto and removed to a distance therefrom in the path of the issuing stream so as to subdivide the latter, the slot in the nozzle having a substantial width to prevent clogging with debris.

2. The combination with a slotted fiat spraying nozzle, of a cutter mounted thereon and consisting of an obstacle in the path of the issuing stream which will be struck thereby for the purpose of breaking the stream, said cutter being removed a short distance from the slot in the nozzle, and said slot being of substantial width to prevent its clogging with debris, so that the issuing stream may be of substantial size, but will be cut into sheets which will expose a large amount of surface to the air.

3. In combination with a flat slotted nozzle, a yoke mounted over said nozzle, and having a knife edge alined with the slot in the nozzle, at a distance therefrom, said slot in the nozzle being of substantial width to prevent its being clogged by debris.

In testimony whereof I hereunto affix my signature.
